Automatic Configuration of CESM/CCSM4 on Amazon EC2 Cloud
MetadataShow full item record
The goal is to develop a prototype configurator service that automatically creates Amazon EC2 machine instances running on the EC2 Cloud containing ready-to-run configurations of the Community Earth System Model (CESM). The CESM Climate Configurator (C3) service takes in high-level experimental configuration tasks as an XML specification. In the future this will be encapsulated by a web-based graphical user interface. From the high-level configuration input C3 determines the closest match from a list of preconfigured Amazon Machine Images (AMI), and starts an instance (a running AMI on the EC2 cloud). C3 then creates and sends a shell script which finishes the configuration of the instance to the requested experiment, and returns a link to the running instance with the specified simulation ready to run.
